Abstract: This paper deals with the problem of predicting the postbuckling configuration of a thin, inextensional, inelastic ring under external pressure. Previous work has shown that the postbuckling ...

Abstract: The subject of pipe buckling and collapse under combined external pressure and bending is revisited in order to investigate the causes of angled buckles observed in recent experiments and the associated “scatter” in the ...

Abstract: The paper addresses instabilities that can affect long panels with arch cross sections. It is demonstrated that in addition to the classical limit load and bifurcation buckling instabilities, such panels can also develop ...

Abstract: The experimental part of a study which deals with the response and stability of thin-walled tubes under cyclic bending histories is presented (see [7] for theory). Aluminum and steel tubes are ...

Abstract: A relatively simple experimental procedure for establishing the anisotropic yield characteristics of commercially available drawn metal tubes is described. Hill’s [4] extension of the Von Mises ...

Abstract: The initiation and propagation of Lüders-type localized deformation in thin, fine grained steel strips in tension is studied through combined experimental and analytical efforts. Purely elastic ...

Abstract: If a pipeline buckles in the presence of sufficiently large external pressure, a propagating buckle is initiated. The buckle propagates along the pipeline until it encounters a region of low ...

Abstract: The paper describes a series of full-scale collapse experiments using X-42 and X-65 grade steel tubes. The initial geometric imperfections of the tubes were measured using a specially designed ...

Abstract: The collapse of long thick-walled tubes under external pressure is studied both experimentally and analytically. A two-dimensional nonlinear formulation of the problem is presented. The formulation ...
